If you are pursuing welding as a new career or are already a seasoned welding technician looking to upgrade your skillset, learning flux core arc welding (FCAW) is an excellent idea. One of the most popular among the many welding processes, flux core welding tends to be highly productive and economical.First developed a few years after World War II, flux core welding offered an alternative to manual metal arc welding, better known as stick welding. Its primary advantage over stick welding is its continuously fed wire electrode. And there are other benefits to the FCAW method. Read on to discover them.En savoir plus -
Welding is a vital process in various industries, enabling the fusion of metals to create strong and durable joints. Among the many factors that contribute to a successful welding, the choice of welding wire plays a crucial role. Solid wire and cored wire are two popular options used in welding applications, each with its distinct advantages and drawbacks. In this blog post, we will delve into the dissimilarities between solid wire and cored wire, shedding light on when and where to use them.En savoir plus -
Every welder wants to save time and money, but no one wants to compromise on the quality of a weld. Losing a client or job over a faulty weld is the last thing most welders want. Perhaps one of the best ways to save money and time on your welding projects is to consider the best applications for flux cored welding wire for MIG welding applications.When it comes to MIG welding, welders typically need to use a shielding gas in order to protect the weld pool from contamination. Certain metals require different shielding gases. Steel uses CO2, but thin steel uses a mixture of 75% Argon / 25% CO2. Argon alone is used for aluminum.In the case of flux cored welding wires, a shielding gas is not necessary since the flux inside of the wire produces a shielding gas when it melts in the weld pool. This can save on both time and overhead cost.En savoir plus -
Flux-cored arc welding is an expansive process with many wire types: gas-shielded, self-shielded, all-position, in-position, carbon steel, HSLA steel, stainless steel, and more. If you ever feel overwhelmed by the sheer number of flux-cored wires in the welding marketplace, consider turning to AWS or CWB filler metal specifications. Often, these technical documents have electrode classification systems that help you compare products and descriptions of the intended uses of certain wire classifications.En savoir plus -
Flux-Cored Arc Welding (FCAW) utilizes a continuously-fed tubular electrode, electrical power to melt the electrode, and may or may not use shielding gas from an externally supplied source when depositing material in the weld joint. The flux-cored electrode is a composite tubular filler metal consisting of a metal sheath with a core of mineral compounds and powdered metals. The resulting weld bead is covered by a residual slag (melted and solidified flux) which helps to protect and shape the finished weld, and is generally easily removed upon completion of the weld. Flux Cored Welding combines the high productivity of MIG welding using a solid electrode with the ability to weld on more contaminated base material. When compared with MIG welding, higher deposition rates are possible, especially when welding out of position.En savoir plus -
Have you wondered, "What is flux core welding?" or "What is a flux core welder?" Flux core welding, also known as flux-cored arc welding (FCAW), is a type of welding that uses a continuous hollow wire electrode to meld metals and other materials together. Flux core welding is suitable for materials contaminated with dirt and rust, making it ideal for outdoor and contaminated environments.There are two types of flux-cored arc welding: gas-shielded and self-shielded. Gas-shielded FCAW is similar to gas metal arc welding (GMAW), while self-shielded FCAW does not require an external shielding gas.FCAW is commonly used in the construction industry due to its high welding speed, portability and ability to be used outdoors. Flux core welding has advantages such as increased mobility, high deposition rate and versatility, but also has disadvantages such as fumes, cleanup and higher equipment costs.Keep reading to learn more about flux core welding basics and processes.En savoir plus -
When it comes to welding, choosing the right wire is crucial for achieving the desired results. Two popular options are flux-cored wire and solid MIG wire. Both have their own unique characteristics and are used for different purposes.Flux-cored wire is known for its ability to weld in windy conditions and in areas without a clean environment. On the other hand, solid MIG wire is preferred for its smooth and consistent welds.But which one is better for your project? This article will explore the differences between flux-cored wire and solid MIG wire, including their pros and cons, so that you can make an informed decision.En savoir plus -
Flux cored arc welding (FCAW), also know as dual shield welding, is a semi-automatic arc welding process that is similar to metal active gas (MAG) welding. FCAW uses a continuous wire fed electrode, a constant-voltage welding power supply, and similar equipment to MAG welding. The process was first developed in the 1950s as an alternative to manual metal arc (MMA) welding which is also called stick welding. FCAW overcomes many of the restrictions associated with MMA, since it uses a continuously fed wire electrode.Flux core arc welding usually uses a shielding gas similar to that used by MAG welding, but it can also be performed without a shielding gas. It is more productive than MAG welding.En savoir plus -
A flux-cored wire is a type of welding wire that uses an electric arc to fuse two pieces of metal together. It differs from a solid wire in that it has a flux core, which helps protect the weld from oxidation and contamination. Flux-cored wire produces less spatter than solid wire and results in a rounder penetration profile with excellent sidewall fusion.En savoir plus -
Flux-cored arc welding (FCAW or FCA) is a semi-automatic or automatic arc welding process. FCAW requires a continuously-fed consumable tubular electrode containing a flux and a constant-voltage or, less commonly, a constant-current welding power supply. An externally supplied shielding gas is sometimes used, but often the flux itself is relied upon to generate the necessary protection from the atmosphere, producing both gaseous protection and liquid slag protecting the weld.En savoir plus -
Flux-cored arc welding (FCAW) wires certainly aren't new, but like any part of the welding process, understanding them can be confusing—without the right information. Becoming acquainted with some basics, including the most appropriate applications, general classifications and characteristics, and advantages and limitations, of flux-cored wires can yield significant results. With more knowledge you can choose and use flux-cored wires confidently for your own welding applications.Flux-cored wires have been around since the 1950s and are available in two main versions: gas-shielded and self-shielded. Both types are composed of an outer sheath and are filled with flux, a compound that is a mixture of alloys and deoxidizers, the latter of which are necessary to protect the weld from contaminants.As their name implies, gas-shielded flux-cored wires require an external shielding gas supply to protect the weld; self-shielded wires do not. The flux in self-shielded wires generates the shielding gas, which makes these wires highly portable and ideal for outdoor welding applications, such as structural steel, shipbuilding, and bridge construction. Common applications for gas-shielded flux-cored wires include general fabrication, pressure vessels, petrochemical piping, and heavy-equipment manufacturing.En savoir plus -
MIG welding and flux-cored welding possess different characteristics that welders must evaluate when selecting which process to use. To achieve the best results, consider the following factors: thickness of the material, proper shielding gas, wire feed speed and voltage settings, location of the jobsite, and weld appearance.There is no one-size-fits-all welding solution, and all of the above variables will affect wire selection. This article will help the novice or occasional welders understand the basics of solid and flux-cored wire and how to maximize their advantages.En savoir plus
